With flesh so sweet to eat!

See the TURTLE of Enormous Girth
On his shell he holds the Earth.
His thought is slow, but always kind.
He holds us all within his mind.

I would say that Dragon Age: Origins has some nice party interactions. It has a four person party and a combat system sort of similar to Baldur's Gate. This year Pillars of Eternity came out and features party mechanics and a camera view like the old Baldur's Gate games and is delightful.
